Title: Improvements in and relating to the ignition of electric discharge apparatus
IPC: H01J13/48
Filed: 1938-01-22
Abstract: 501,174. Metal - vapour apparatus. AKT.-GES. BROWN, BOVERI, & CIE. Jan. 22, 1938, No. 2200. Convention date, March 26, 1937. [Class 39 (i)] In electrostatic ignition devices for electric discharge apparatus of the mercury pool type, the surface of the insulator carrying the ignition electrode which is in contact with the mercury pool is kept clean by a member which performs a rubbing movement thereover during operation of the electric discharge apparatus. The drawing shows thebottom 1 of the metal casing of a rectifier to which the cathode plate 3 is secured by an insulator 2. An insulating tube 5, closed at the top and having a conducting lining 6, passes through the plate 3 and mercury pool 4. Voltage is supplied to the lining 6 by a cable 7. A sleeve 8 is mounted about the end of the tube 5, and may be of a material such as quartz floating on the mercury in which case tangential slots or radial slots with fins on one edge are provided at the lower end. If the material of the sleeve is tungsten &c. which sinks in mercury the slots are provided at the upper end. The reaction on the sleeve produced by the starting arc causes the sleeve to rotate in contact with the tube 5 and keep the surface thereof clean. In addition spot-fixing devices either on the sleeve or separate therefrom may be arranged to produce movement of the sleeve. The spotfixing devices may be fixed on the rotating sleeve, or may be formed separately by conducting or insulating members fixed to the bottom of the cathode chamber and projecting above the pool and arranged tangentially to the rotating sleeve. In an alternative form, the ignition electrode may be disposed outside the wall 2, in which case the rubbing member contacts with the inner surface of this wall.

Abstract: 431,034. Typewriters. TRIUMPH WERKE NURNBERG AKT.-GES., 212, F³rtherstrasse, Nuremberg, Germany. Jan. 23, 1935, No. 2260. Convention date, March 5, 1934. [Class 100 (iv)] Letter-spacing mechanism.-A one-way coupling for the escapement-wheel, permitting noiseless return of the carriage, comprises balls or rollers arranged between a notched disc and a slotted ring secured to the carriage feedpinion and escapement-wheel respectively. In the coupling shown in Figs. 1 and 2, the feedpinion 2 is formed on a loose sleeve 3 which is mounted on the shaft 1 of the escapementwheel 6 and is connected by claws 4 to a disc 8 arranged in a ring 7 secured to the escapementwheel, the disc and ring being formed with notches 9 and inclined slots a .. f co-operating with balls or rollers 10. The number of notches is equal to the number of escapementwheel teeth, and each notch is formed with flat and steep parts 9b, 9a. A cap 12 encloses the coupling. During letter-spacing, the disc turns in the direction of the arrow A, and the descending rollers co-operate with their slots to couple the escapement-wheel, the ascending rollers resting at the bottom of their slots. During carriage-return, the disc turns in the direction of the arrow B, the flat parts 9b of the notches 9 push the rollers into the slots, and the escapement-wheel is uncoupled. To adapt the coupling for use with an escapement-wheel affording half the normal letter-spacing movement, without doubling the number of troughs in the disc, alternate slots in the ring are displaced by one-half the pitch of the troughs in the disc.

Title: Improvements in or relating to treatment of hydrocarbons
IPC: C07C9/14
Filed: 1939-01-24
Abstract: 525,554. Alkylation and isomerization of paraffins. TEXACO DEVELOPMENT CORPORATION. Jan. 24, 1939, No. 2436. Convention date, Feb. 17, 1938. [Class 2 (iii)] Anti - knock motor fuel hydrocarbons are obtained by reacting isobutane with olefines in presence of normal butane and sulphuric acid, or aluminium chloride or bromide as alkylating catalyst, the isobutane being maintained in excess of the olefines, removing and fractioning the unreacted hydrocarbons to separate isobutane from butane, converting the normal butane to isobutane in presence of aluminium chloride or bromide or their hydrocarbon compounds, with or without a little hydrogen chloride, as isomerizing catalyst and returning both the separated and the produced isobutane to the alkylating stage. The process is especially applicable to an olefine-containing C 4  fraction of cracking still gases. The alkylation temperature may be from -40 to 170‹F., the reaction time 10 min. to 2 hrs. ; the isobutane may be up to 20 : 1 of the olefines. The isomerization temperature may be atmos. to 200‹F., the time of reaction a fraction of an hour to more than a day. For example, isobutane, butane, and olefines are pumped through one or more pipes 1 along with recycled isobutane from a pipe 53 to a reaction chamber 3 supplied with 94 per cent. sulphuric acid through a pipe 5 ; the mixture at a pressure of 50-100 lb. is passed through one or more reaction chambers 12 to a separator 18 ; acid is returned by a pipe 20 to the pipe 1 ; the oil is taken by a pipe 23 through a pressure-reducing valve 24 to an evaporator 25 which may or may not be heated ; the liquid hydrocarbon products are withdrawn through a pipe 27 ; the unreacted normally gaseous hydrocarbons are passed through a pipe 29 and a condenser 30 to an accumulator 31 from which fixed gases e.g. C 1  and C 2  hydrocarbons may be released through a pipe 32. The normal butane is pumped through a pipe 34 to one or a series of isomerization chambers 36 supplied with aluminium bromide hydrocarbon compound through a pipe 38 ; when about 50 per cent. has been converted the products are pumped through a pipe 41 to a settling or separation chamber 44 ; here the catalyst settles out-or the hydrocarbons are distilled therefrom-and is withdrawn through a pipe 45 ; the hydrocarbons are taken by a pipe 46 to a fractionator 48 to separate an isobutane fraction which is withdrawn through a pipe 51 to a reboiler 50 ; from this the isobutane fraction is returned by the pipe 53 to the pipe 1, vapours are returned to the fractionator by a pipe 52 ; higher and lower boiling fractions are taken from the fractionator through pipes 55 and 56. Specification 516,780 is referred to.

Title: Improvements relating to high speed electronic impulse counters
Inventor: BRADY THOMAS WILLIAM
IPC: H03K29/00
Filed: 1953-01-28
Abstract: 721,814. Multi-stable state circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 28, 1953, No. 2457/53. Class 40 (6). A multi-stable state pulse counting circuit comprises a chain of multi - cathode sequence tubes in which when the discharge is removed from the penultimate cathode in a given tube subsequent to its transference to the final cathode of that tube a pulse is applied to the next succeeding tube in the chain. The Figure shows a batch counting circuit in which pulses to be counted are applied at input 14 to a cathode-coupled flipflop circuit comprising valves V1, V2 the resultant negative-going pulses at the anode of valve V2 being applied directly and via a delay network in unit 20 to the guide electrodes 12, 13 of a sequence. tube T1 as described in Specification 691,623. The application of each pulse to guide electrodes 12, 13 advances the discharge one step in tube T1 until when the discharge is removed from cathode 9 the resulting negative pulse at cathode resistor R9 is differentiated in network 17, 18 and the resulting sharp negative pulse cuts-off valve V4 of the flip-flop circuit comprising valve V4, V5. The negative pulse thus produced at the anode of valve V5 is passed to the input flip-flop circuit corresponding to valves V1, V2 of the next stage of the counting chain. The stages are set to a given count by the selector switches 16 so that if the stage shown is set, for example, to a count of 6, when the discharge reaches cathode 6 a positive pulse is produced across resistor R6 and applied to line 25 simultaneously with pulses from the corresponding cathode resistors in the other stages. This coincidence of pulses causes flip-flop circuit 22 to change-over to produce a negative pulse at the anode of valve V6 and thus at the final cathode 10 of each sequence tube to re-set each tube to the zero position. Specification 704,816, [Group XIX], also is referred to.

In a first orientation, a pin (20) Figs. 3B and 9A (not shown) on the playipiece 2 cooperates with a socket (36) Figs. 6 and 9B (not shown) in the base member 30 to complete a circuit including a battery and a lamp 42, whereby the lamp is energised to illuminate the Figure 6. To ensure that this particular orientation is not easily recognisable, the playpiece and the base member are also provided respectively with dummy pins (22) and sockets (34) indistinguishable in appearance from their operational counterparts; thus, in a second orientation the dummy elements cooperate either with each other or with an operational element and the lamp is not energised. In the playing of a game, one player arranges the base member in a desired position and another player places the playpiece upon the base member, success in the game being related to the illumination or non-illumination of the Figure 6. A bell or buzzer may replace the lamp 42, which itself may be mounted on the surface of the playpiece. or even at a remote location. Other cooperating means, e.g. of the magnetically interacting type, may replace the pins and sockets. The playpiece may be of translucent plastics material, or may be made of a phosphorescent material for absorbing light and glowing in the darkness.
